Pro Compass is the latest app from Hunter Research and Technology, developer of the popular Theodolite app series. Pro Compass replicates the look and feel of classic pocket compass hardware in use since the 1800s, adding modern features and technologies. The app uses advanced OpenGL graphics (normally reserved for games) to render 3D floating compass hardware for realistic operation.
Pro Compass offers nine different compass modes with needle, pointer, and rosette styles capable of displaying degrees, quads, or mils. The needle mode shows a proper "direct read" display with a North-South needle and reversed East-West convention. In all display modes, Pro Compass shows both magnetic and true direction simultaneously, with a rotating outer true ring that is automatically adjusted for local magnetic declination.
Pro Compass displays location and altitude, with decimal, degree-minute-second, UTM, and MGRS position formats. An optional Datum Pack adds over 220 geodetic datums covering regions and countries on all continents around the world. Pro Compass also contains a built in two-axis inclinometer that drives two independent bubble levels and a bullseye level. The inclinometer has angle readout dials for each axis, making it useful for many different types of measurements including slopes, pitches, sight lines, and geological angles like dip and strike.
